ETIENNE DERBEO, OF SAN FRANCISCO, CALIFORNIA.

PU LVERIZER AND AMALGAIVIATOR.

SPECIFICATION forming part of Letters Patent No. 395,957, dated January 8, 1889.

Application filed January 31, 1888. Serial No. 262,574. (No model.)

To all 1.0710120 it hwy concern.-

Be it known that l, ETIENNE DERBEC, of

San Francisco, in. the county of San Francisco and State of California, have invented certain new and useful Improvements in Combined Ore Pulverizers and Amalgamators, of which the following is a specification.

My in "ention relates especially to ore grinders and amalgamators for pulverizin g ores and amalgamating the precious metals.

In the accompanying drawings, ili'orming part of this specification, Figure lis a side elevation, partly inseetion, of my ore crusher and amalgamator. Fig. 2 is a plan or top view. Fig. 3 is a cross-section.

Like figures and letters indicate corresponding parts in all the places where they occur.

A is the bed of the tank, which may be made of masonry or concrete and suitably supported upon iOl'lgiilltlllltll and cross timbers. The face of the bed is lined with metal plate or plates 1-3, with smooth plane upper surface, and when formed in sections the edges of the plates abut one against each other, forming a tight joint.

The rollers (l are solid or hollow cylinders with plane smooth surfaces, and are arranged at suitable distances apart in the rectangular frame I), having their journals in bearings within the side rails thereof.

A shaft, E, extends across the upper end of the roller-frame, suit-ably supported by the,

uprights i E and a saddle, F,having'forked aims F straddles this shaft E midway be tween the ends thereof, the shaft being suitably braced by the rods G (i at each side of the roller-frame, as shown.

Over the shaft E is placed a rock-shaft, II, having suitable end bearings in boxes II Thisshaft passes through a boss, F in the top of the saddle F, to which it is keyed. A

crank, L, is attached to the end of the rockshaft II, and a connecting-rod, I, from the crank L connects it with the wrist-pin f, so that when power is imparted to the wrist wheel a reciprocating motion will be given to the rollers on the bed of the machine.

In the lower end of the bed is constructed a transverse groove or channel, in which the heavierparticles of ore and quicksilver settle for cleaning up, and the debris and water pass off through an overflow pipe. (Not shown.)

In practice the ore is received from the fluine or sluice K and passes down upon the bed-plate, which has previously received a suitable supply of quicksilver. Then the heavy system or series of rollers is set in motion, passing slowly to and fro or backward and forward over the ore, crushing and pulverizing by the weight of the rollers and amalgamating the precious metals without grin ding or touring the quicksilver.

Ilavin g thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination, with a solid bed with inclosed sides and overlaid plates, of the system or series of pressln'e-rollers, a frame within which they are mounted, said frame being provided with a transverse bar at the upper end thereof, a rock-shaft with forked arms engaging said bar, and means, substantially as described, for operating the rock-shaft, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
